Demands continue to rise on our natural water resources

Conserving, protecting and channeling clean water is more than a vital part of our business—it’s an ethical obligation for sustainable development. Throughout the country we’ve constructed a variety of water infrastructure-related projects, from dams and flood control structures to reservoirs, zero-liquid-discharge (ZLD) wastewater treatment plants and lined canals for agricultural irrigation.

Trenchless and Pipe Rehabilitation Services

Thanks to its top-notch innovation, experience and customer service, Kenny Construction Company, a Granite subsidiary, is a national leader in the underground infrastructure industry. In addition to conventional techniques in underground construction, Kenny continually researches new technologies to serve an owner’s needs. The company holds licensing agreements for new trenchless technologies, including cured-in-place pipe (CIPP) rehabilitation, cured-in-place manhole lining (CIPMH) and glass-fiber reinforced plastic (GRP) pipe renovation systems. These systems can improve the life of existing pipelines by improving structural and hydraulic characteristics while reducing project costs.

Water Transmission & Delivery

Over the last century, Granite has performed a vital role in constructing municipal and private water/wastewater distribution systems. Our expertise includes water mains, pipelines, sewers storage reservoirs and pumping stations. We proudly offer the capability and in-house resources for any size project.

Safety Enhancements for Dams, Locks and Reservoirs

Many complex factors go into assessing long-term viability of water flood control structures, including engineering, safety concerns, aquatic biology, water supply, fish and river restoration and land conservation. In the last 30 years, more than 10 dams have undergone removals. As the number two ranked contractor in the U.S. for dams and reservoirs, we offer intricate understanding of successfully constructing and deconstructing these structures.

Benefits of Canal Lining

Canals can lose 30 to 50 percent of their irrigation water through seepage. Canal-lining technology such as compacted earth, reinforced concrete and buried geomembranes greatly aid in conservation. They also support agricultural lands and riparian habitat areas for beneficial use of water resources. Granite offers custom trenching as well as canal-lining equipment and techniques for speedy and cost-efficient solutions.

San Bernardino Arrowhead Tunnels Project

Two 19-foot diameter tunnels were excavated to support a key segment of the Metropolitan Water District of Southern California’s Inland Feeder. The tunnel boring machine (TBM) took more than four years to bore its way through the San Bernardino Mountains, but the project still came in nearly a year ahead of schedule.

Carmel River Reroute and San Clemente Dam Removal

In 2013, Granite was selected to lead the largest dam removal project in California history. The river restoration project involves rerouting the Carmel River into San Clemente Creek at a location upstream of the dam and also permanently removing the dam structure, originally constructed in the 1920s.

Utah Jordanelle Dam and Reservoir

Located on the Provo River about six miles north of Heber City, UT, Jordanelle provides water storage at an upstream site by exchange for Bonneville Unit water in Utah Lake and Strawberry Reservoir. Jordanelle has a capacity of 320,300 acre-feet with a surface area of 3,068 acres.

Gila Bend Zero Liquid Discharge (ZLD) Water Treatment Facility

The design-build zero liquid discharge water treatment facility featured a 2200 MW combined cycle generating station in Gila Bend, AZ. The project included installation of two 100’ AL6XN alloy evaporator towers and three 180,000 gallon Thickener and Clarifier Units.

Folsom Auxiliary Dam Spillway

Granite constructed a concrete gravity dam housing six submerged radial-arm tainter gates and six emergency bulkhead gates to allow water to be released earlier and more safely from Folsom Lake during a high-water event.
